CONNECTION FOR TRACK APPLIANCES.

Specification of Letters Patent.

Patented All. 26, 1919.

Application filed June 3, 1918. Serial No. 237,870.

To all whom it may concern:

Be it lmown that'I, STANLEY W. Harms, United States citizen, residing at Richmond, Indiana, have invented the following-described Improvements in Connections for Track Appliances.

The invention is a connection means for railway track appliances and more particularly for the attachment of derails to the operating rods which operate them or by which they operate some other device, the object being to safeguard such connections against tampering and other advantages hereinbelow disclosed.

In the accompanying drawing- Figure 1 represents a pivoted derail incorporating the invention and shown in perspective in its open position upon the rail;

Fig. 2 is a longitudinal cross-section of the same in a closed position;

Fig. 3 is a cross-section in an open position; and

Fig. 4 a horizontal cross-section through the connection means.

The derail illustrated comprises a base 1 adapted to be spiked to the ties adjacent the rail and a derail block 2 pivoted thereon at 3 whereby it may be swung on and off the rail as will be evident. The rear of this movable track appliance member is provided with a connection lug 4 receiving the bent-over end of an operating rod 5 by means of which it is connected to operate a target or some other track device or by means of which the derail itself can be operated if desired. The rear of said movable member is also equipped with a padlock lug 6, the hole through which'is of an appropriate size to receive a padlock hasp, which when placed therein obstructs the pivotal movement of the derail and looks it in its determined position. The connection lug 4 1s bored to receive the rod 5. and is cross slotted as in- Oopies of this patent may be obtained for five cents each, by addressing the dicated at 7 at right angles to the bore, thus producing a cleft lug structure. The cross slots 7 may be cast or cut in the lug as may be most convenient and the rod-receiving bore therein may or may not extend entirely through the lug as preferred. The end of the operating rod is drilled to receive a cotter pin 8 which is inserted therein, through the slot 7, and then spread apart at its ends as shown in Fig. 3 for retaining it in position. The cross slot is of greater radial dimension than the length of the cotter pin and is relatively narrow as compared to the diameter of the bore and being in fact no wider than necessary to accommodate the cotter, and if preferred, a washer 9. With such dimensions the attachment of the rod to the lug is relatively tamper-proof because a tool of the necessary strength and thinness to be capable of entering the slot and straightening the spread-apart. cotter within the slot is not likely to be convenient. The cotter may however be quickly removed by a suitable pair of thin-jawed pliers. It will be apparent that the cotter pin 8 represents the preferred form of attachment means, other equivalent fasteners being also capable of use without departing from the invention.

Claim.

The combination with the movable member of a track appliance, of a connection lug thereon provided with a bore and with a cross-slot intersecting the same, said bore being adapted to receive an operating rod, and a fastener engaging said rod and occupying the cross-slot, said slot being of rela tively narrow width with reference to the diameter of the bore and of greater radial dimension than the fastener.

In testimony whereof, I have signed this specification.
